Thanks.
Managed 90 minutes off-road on the bike today.
My "comeback" had all been road or the canal towpath in road shoes.
yesterday I spent all day in my La Sportiva Cross Country whilst watching and then I thought they'd be Ok to race in.
I think their low heel profile perhaps just put a bit more load on my calf and Achilles and so I think I'll just have to stick to road shoes for the time being. Hopefully be back running Tuesday or Wednesday.
